Senior Systems Engineer, IT Operations and Infrastructure

Firestorm•San Diego, CA

3d•$116,000 - $138,000•Onsite

About The Position

Firestorm builds uncrewed aircraft and the manufacturing network that produces them: full-capability plants, deployable xCell edge factories, and forward-deployed sites that stand up production near the point of need. Crucible is the software that runs that network. It runs in the cloud, inside a factory, and air-gapped in classified environments. At the edge, Crucible has to operate reliably on local compute, connect to factory equipment, and keep working when cloud infrastructure and internet connectivity are unavailable. We are hiring a Systems Engineer to support critical business operations, infrastructure in the cloud and on-premise, Microsoft 365 GCC-High, Amazon-Gov and other systems.

Requirements

U.S. Citizenship and ability to obtain and maintain a U.S. Government security clearance
Deep operational proficiency with Linux distributions (RHEL, Ubuntu, Rocky) and/or Windows Server environments, including OS hardening, kernel tuning, and troubleshooting.
Strong practical scripting skills in at least one language (Bash, Python, or PowerShell) to automate administrative tasks and repetitive workflows.
Solid understanding of core networking protocols and services (TCP/IP, DNS, DHCP, VLANs, HTTP/S, SSH, VPNs, and firewall rules).
Hands-on experience administering virtualized infrastructure (VMware ESXi/vCenter, Hyper-V, KVM) or public cloud platforms (AWS, Azure, or GCP).
Experience configuring and operating enterprise monitoring, logging, and APM tools (e.g., Prometheus, Grafana, Datadog, Splunk, ELK, or CloudWatch).
Experience with Microsoft GCC-High environments, AWS-Gov and similar secure environments that have CUI and ITAR data
Experience with CMMC v2 and NIST 800.171 compliance needs

Nice To Haves

Working knowledge of configuration management and provisioning tools such as Terraform, Ansible, Puppet, or SaltStack.
Familiarity with Docker and container orchestration platforms (Kubernetes, ECS).
Experience managing enterprise directory services, IAM, and SSO protocols (Active Directory, Entra ID, Okta, SAML, LDAP).
Direct experience designing, executing, and auditing multi-site backup strategies and failover simulations (e.g., Veeam, Zerto, AWS Backup).
Experience with High Performance Compute (HPE, Supermicro)
Experience with Enterprise Storage (NetApp)

Responsibilities

Deploy, configure, patch, and manage physical servers, virtual machines, cloud instances (AWS, Azure, GCP), and enterprise storage.
Implement and maintain observability tooling (e.g., Datadog, Prometheus, Grafana, CloudWatch) to track system performance, resource utilization, and uptime.
Serve as an escalation point for system outages and critical alerts; lead root-cause analysis (RCA) and document post-mortems to prevent recurrence.
Write and maintain scripts (Bash, Python, PowerShell) and infrastructure-as-code configurations (Terraform, Ansible) to automate routine operational tasks and deployments.
Monitor core network services (DNS, DHCP, VPNs, routing, and firewalls) to maintain secure, low-latency communication across environments.
Design, schedule, test, and verify automated backups, data replication, and disaster recovery plans to ensure strict Recovery Point and Recovery Time Objectives (RPO/RTO).
Apply system hardening standards, manage access control (IAM/Active Directory/SSO), audit system logs, and remediate CVE vulnerabilities in coordination with the security team.
Analyze compute, storage, and network trends to optimize system performance and forecast hardware or cloud resource scaling needs.
Author and update runbooks, system architecture diagrams, standard operating procedures (SOPs), and operational workflows for team use.
